Definitions

  • the invention relates to a device for compacting concrete in a formwork for a concrete wall straight or curved in plan view.
  • Container walls made of reinforced concrete in sewage treatment plants should have a particularly good quality of concrete in order to be resistant to aggressive waste water. It is important that the concrete in the correct composition is poured into the formwork without demixing and that it is properly compacted. As practice shows, especially when compacting concrete, mistakes are made that can no longer be remedied. In addition, compacting the concrete is a time-consuming and tedious job.
  • a plurality of vibrating bottles are arranged at intervals from one another on a device which can be moved along the formwork, and a gear motor for lowering and lifting the vibrating bottles is also provided, which can be controlled by a programmable controller.
  • the vibrating bottles are detachably connected at intervals to form an internal vibrator; these distances between the vibrating bottles are dependent on the wall thickness of the formwork and the Performance of the individual vibrating bottles designed differently.
  • the internal vibrator is guided on an internal and external reinforcement, and the gear motor and rope pulleys for the internal vibrator are detachably attached to a concrete bucket that can be moved along the formwork.
  • both the geared motor and the rope pulleys are detachably arranged on the device which can be moved along the formwork.
  • the vibrating bottles In order to simplify the penetration of the vibrating bottles into the concrete, they can preferably be pointed at the lower end.
  • a steel tube is attached to the upper part of the vibrating bottles, through which a power cable for a vibrating motor is passed.
  • the vibrating bottles end at the top on an elastic hollow strand, which is also capable of absorbing electricity.
  • An internal vibrator is therefore used to compact the concrete, which consists of several vibrating bottles that are spaced apart and coupled to one another.
  • the internal vibrator is lowered into the formwork on two thin steel cables using a special geared motor.
  • the internal vibrator is on the outer and so that the vibrating bottles are immersed in the right places in the concrete
  • FIG. 1 shows a section of a formwork 10 from the outer and inner formwork wall 12, the outer formwork being neglected in the drawing for reasons of clarity.
  • An internal vibrator 16 protrudes into a concrete bed 14 largely filling the formwork 10 from here three vibrating bottles 18 arranged at a distance n from one another. The latter are each attached at their upper end via a hose 20 to a crossbar 22; the hoses 20, in which the power supply to a vibrating motor, which is not visible, are built in, enable the vibrating bottles 18 to vibrate freely.
  • the horizontal crossbeam 22 is guided on both sides by two guide springs 24 on outer and inner reinforcements and suspended on both ends on steel cables 26.
  • the guide springs 24 are shaped in such a way that the internal vibrator 16 cannot get caught on the reinforcement during lowering and lifting within the formwork 10.
  • Two rope pulleys 30 are releasably attached to a concrete bucket 28 which can be moved along the formwork 10 and has an opening mechanism 29.
  • a small work platform 36 is attached to the concrete bucket 28 on the left in FIG. 1. When filling the concrete 14, it serves as a location for operating the concrete bucket 28 and the associated undercarriage.
  • the internal vibrator 16 and the associated control system can also be operated from this work platform 36. If a corresponding layer of concrete 14 is filled into the formwork 10, it must be compacted.
  • the vibrating bottles 18 must remain in it for a certain time in order to be able to be slowly lifted out.
  • the immersion depth a for the vibrating bottles 18 in the concrete 14, the residence time in the concrete 14 and the speed at which the vibrating bottles 18 are to be lifted out of the concrete 14 are set again via the control on the geared motor 34.
  • a person operating the system then only has to move the concrete bucket 28 to a specific intended location on the formwork 10 and to lower the internal vibrator 16. The compression itself then runs automatically and without errors.
  • the anchoring is always made at the same intervals. It is expedient to provide the internal vibrator 16 with a number of vibrating bottles 18 corresponding to the required wall thickness, in such a way that the concrete 14 is compacted along the formwork 10 - from one anchor to the next is; In this way, the concrete 14 can be compacted in the formwork 10 quickly, easily and without errors.
  • the formwork 10 of FIG. 2 is half-filled with concrete 14.
  • a gantry-like device 40 can be seen, which can be moved along the formwork 10 on a running rail 46 by means of an electric running gear 42 and pulley-like rollers 44.
  • the device 40 with the concrete bucket 28 attached at the top left serves to pour the concrete 14 between the formwork walls 12, 13.
  • vibrating bottles 18 almost completely submerged, of which only the first one is visible.
  • a steel tube 48 is welded to a screw-off cap, which encloses the power cable 50.
  • This steel tube 48 can - not shown - have the diameter of the vibrating bottle 18, 18 a .
  • Each vibrating bottle 18 a is guided by means of a power cable 50 over two rope pulleys 52 of the device 40. The distance between these rope pulleys 52 is adjustable.
  • the power cables 50 are connected to each other on a light profile 54 with junction box 56. From this junction box 56, a power cable 50 a leads to a current converter 58, which is attached near the concrete bucket 28 to the device 40; all vibrating bottles 18 are supplied with power. In addition, 28 lighting devices 60 are provided on the concrete bucket; the compaction process can only be carried out properly if the concrete 14 to be compacted in the formwork 10 is illuminated.
  • Two thin steel cables 26 a hang down from the profile 54 and are connected at the other end to a light geared motor 34 which has two cable drums.
  • the control for the geared motor 34 is programmable.

Abstract

Dispositif pour le compactage du béton dans un coffrage pour mur en béton, dans lequel plusieurs tubes pervibrateurs (18, 18a) sont montés suspendus, séparés par des intervalles (n), sur un dispositif mobile (22, 40) pouvant se déplacer le long du coffrage; en outre, il est prévu un moteur à engrenages (34), à commande programmée, destiné à abaisser et à relever les tubes pervibrateurs. Ces tubes (18) sont connectés amovibles, séparés par des intervalles (n), à un vibrateur interne (16), lesdits intervalles étant dimensionnés différemment, en fonction de l'épaisseur de paroi du coffrage (10) et du rendement des tubes individuels; le vibrateur interne est guidé sur une armature intérieure et extérieure.
